Shared Call Appearance (SCA)
You can use SCA feature to share an extension which can be registered on two or more IP
phones at the same time. The shared line is indicated by a different line icon.
In the following figure, the first line is private and the second line is shared:
If two phones share a line, an incoming call to this extension will cause both phones to ring
simultaneously. The incoming call can be answered on either phone but not both.
This feature is very useful in the boss and secretary scenario. For example, the secretary can
share the boss's extension on her phone. When there is an incoming call to the extension of the
boss, both the phones of the boss and the secretary will ring simultaneously. Either the boss or
the secretary can answer the call. Calls on the shared line can be placed on hold, barged in or
retrieved from another shared phone.
Configuring SCA Feature on the IP Phone
You can configure a primary account on the IP phone and other alternate accounts on the other
IP phones. In a SCA Hybrid Key System scenario, you can automatically assign multiple DSS keys
with Line type for a registered shared line on the phone (If auto linekeys feature is enabled). For
example, party A, party B share the account 4603, phone A registers the primary account 4603
and assigns line key 1 and line key 2 for the account 4603, phone B registers the alternate
account 4603_1 and assigns line key 1 and line key 2 for the account 4603_1, phone C registers
the account 4604.
